Could you try latest cvs version and send me again the output - maybe there are some problems with 64bit. I havn't yet had the chance to test it on a 64bit machine.
 [2002-08-10 10:16 UTC] kalowsky@php.net
Marking as feedback until Sebastian responds.
 [2002-08-11 11:54 UTC] nohn@php.net
This bug has been fixed in CVS. You can grab a snapshot of the
CVS version at http://snaps.php.net/. In case this was a documentation 
problem, the fix will show up soon at http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites.
Thank you for the report, and for helping us make PHP better.

PHP compiles fine with exif now. There are still some compiler warnings, but it seems to run.

Looks like Derick fixed this in CVS.  Try it a new snapshot :P
